   Pupito — notificaciones (public/js/notifications.js, docs/NOTIFICATIONS.md): la campana de la
   barra superior con su insignia, el panel (desplegable en el ordenador, hoja a todo el ancho en el
   móvil), el aviso pequeño en vivo y el diálogo «Invitar a tu sala». Base común y, debajo, cada tema
   bajo :root[data-style='brutal'] / :root[data-style='retro'] (claro y oscuro). El retro está
   retirado por ahora (public/js/theme.js): sus reglas quedan aquí, sin efecto, para cuando vuelva.
